Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine needle technology, and in particular to a fixed-length cutting device for flat knitting machine needle production. Background Technology

[0002] Flat knitting needles are tools used on flat knitting machines for weaving, mainly used to thread the sewing thread and penetrate the fabric. The fixed-length cutting device for flat knitting needle production is a device used to precisely cut the flat knitting needles during the production process.

[0003] The common cutting method for fixed-length cutting devices used in the production of flat knitting needles is to manually measure the length of each needle before cutting it. This method has low work efficiency, and because manual measurement cannot accurately measure the length, the cut needles may not meet the requirements and become unusable, thus increasing costs.

[0004] Therefore, to address the issues of low work efficiency and increased costs caused by manually measuring and cutting the knitting machine needles, six sets of holes and slots on the placement seat and limit seat allow for the simultaneous measurement and cutting of six knitting machine needles, increasing work efficiency. Furthermore, an electric push rod drives the limit seat and limit block to move up and down, allowing the limit block to move on the surface of the measuring rod. By ensuring the limit block surface is parallel to the markings on the measuring rod, the length of the knitting machine needle can be accurately measured, avoiding costly errors caused by measurement mistakes. Utility Model Content

[0005] To overcome the common problem of low work efficiency and increased cost caused by manually measuring and cutting the needles of the flat knitting machine.

[0006] The technical solution of this utility model is as follows: a fixed-length cutting device for the production of flat knitting needles, comprising a base, a support block, a placement seat and an extension plate. The support block is symmetrically installed on the outer side wall of the base. The placement seat is installed on the top outer wall of the base at the middle position. The support block has a sliding groove for the extension plate to be slidably installed and connected. A positioning mechanism is installed on the top of the base. A cutting mechanism is installed on the side of the extension plate. A fixing mechanism is installed on the top of the base.

[0007] Preferably, the positioning mechanism includes a measuring rod, a connecting block, an electric push rod, a fixing block, a limiting block, and a limiting seat. The measuring rod is symmetrically installed on the top outer wall of the base, the connecting block is symmetrically installed on the side outer wall of the extension plate, the electric push rod is symmetrically installed on the top outer wall of the base, the fixing block is fixedly installed at the output end of the electric push rod, the side outer wall of the fixing block is connected to the side outer wall of the connecting block, the limiting block is installed on the side outer wall of the fixing block, and the measuring rod is slidably installed inside the limiting block.

[0008] Preferably, a limiting seat is fixedly installed between the two fixing blocks. The limiting seat is located directly above the placement seat. The outer side wall of the limiting seat has six sets of holes at equal intervals, and the top outer wall of the placement seat has six sets of placement grooves aligned with each other.

[0009] Preferably, the cutting mechanism includes a push block, a cutting blade, an L-shaped block, a support plate, a bidirectional lead screw, and a drive motor. The side of the connecting block is provided with a sliding groove for the push block to slide on, and the cutting blade is installed on the outer side wall of the push block.

[0010] Preferably, an L-shaped block is installed on the top outer wall of the push block, a support plate is installed on the top outer wall of the extension plate, a drive motor is installed on the side outer wall of the support plate, the output end of the drive motor passes through the support plate and is connected to a bidirectional lead screw, and the bidirectional lead screw is rotatably connected to the support plate.

[0011] Preferably, the fixing mechanism includes a connecting plate, a fixing plate, an electric telescopic rod, a movable block, and an electromagnet. The connecting plate is installed on the top outer wall of the fixing block, and the fixing plate is fixedly installed on the top outer wall of the connecting plate.

[0012] Preferably, an electric telescopic rod is installed on the top outer wall of the fixed plate at the middle position. The output end of the electric telescopic rod passes through the fixed plate and is connected to the top outer wall of the movable block. A sliding groove is provided on the side outer wall of the connecting plate for the movable block to slide. An electromagnet is installed on the bottom outer wall of the movable block.

[0013] The beneficial effects of this utility model are:

[0014] 1. With a fixing mechanism, during use, when the needle is placed above the placement seat and passes through the limiting seat, the electric telescopic rod extends, pushing the movable block downward. This causes the movable block to move the electromagnet downward, where it comes into contact with the tip of the needle, applying downward pressure to fix the needle in place. Then, the electromagnet is energized, generating magnetic force. After the cutting blade cuts the needle, the resulting debris and cut needle waste are attracted by the electromagnet to prevent them from falling onto the limiting seat and affecting the next cutting effect. Subsequently, the electric telescopic rod retracts, moving the electromagnet upward and placing the waste box below it. The electromagnet is then de-energized, causing the debris and needle waste attracted to the electromagnet to fall into the waste box for easy collection.

[0015] 2. With a positioning mechanism, during use, the needle is first inserted into the upper part of the placement seat through the limiting seat. Then, the electric push rod pushes the fixing block to drive the limiting seat and the limiting block to move up and down, so that the limiting block moves up and down outside the measuring rod to accurately measure the length of the needle, avoiding the need for the needle to be cut to the required length due to human measurement errors.

[0024] The positioning mechanism 5 includes a measuring rod 51, a connecting block 52, an electric push rod 53, a fixing block 54, a limiting block 55, and a limiting seat 56. The measuring rod 51 is symmetrically installed on the top outer wall of the base 1, the connecting block 52 is symmetrically installed on the side outer wall of the extension plate 4, the electric push rod 53 is symmetrically installed on the top outer wall of the base 1, the fixing block 54 is fixedly installed at the output end of the electric push rod 53, the side outer wall of the fixing block 54 is connected to the side outer wall of the connecting block 52, the limiting block 55 is installed on the side outer wall of the fixing block 54, and the measuring rod 51 is slidably installed inside the limiting block 55.

[0025] A limiting seat 56 is fixedly installed between two fixing blocks 54. The limiting seat 56 is located directly above the placement seat 3. Six sets of holes are equally spaced on the outer side wall of the limiting seat 56. Six sets of placement grooves are aligned on the outer top wall of the placement seat 3.

[0026] The cutting mechanism 6 includes a push block 61, a cutting blade 62, an L-shaped block 63, a support plate 64, a bidirectional lead screw 65, and a drive motor 66. The side of the connecting block 52 is provided with a sliding groove for the push block 61 to slide on, and the cutting blade 62 is installed on the outer side wall of the push block 61.

[0027] An L-shaped block 63 is installed on the top outer wall of the push block 61, a support plate 64 is installed on the top outer wall of the extension plate 4, a drive motor 66 is installed on the side outer wall of the support plate 64, the output end of the drive motor 66 passes through the support plate 64 and is connected to the bidirectional lead screw 65, and the bidirectional lead screw 65 is rotatably connected to the support plate 64.

[0028] The fixing mechanism 7 includes a connecting plate 71, a fixing plate 72, an electric telescopic rod 73, a movable block 74, and an electromagnet 75. The connecting plate 71 is installed on the top outer wall of the fixing block 54, and the fixing plate 72 is fixedly installed on the top outer wall of the connecting plate 71.

[0029] An electric telescopic rod 73 is installed on the top outer wall of the fixed plate 72 at the middle position. The output end of the electric telescopic rod 73 passes through the fixed plate 72 and is connected to the top outer wall of the movable block 74. A sliding groove is opened on the side outer wall of the connecting plate 71 for the movable block 74 to slide and connect. An electromagnet 75 is installed on the bottom outer wall of the movable block 74.

[0030] Working principle: According to Figures 1-3As shown, firstly, the flat knitting needle to be cut is inserted through the hole in the limiting seat 56 and into the placement slot at the top of the placement seat 3. Then, the electric push rod 53 is turned on, causing the electric push rod 53 to push the fixing block 54, which in turn drives the limiting seat 56 and the limiting block 55 to move up and down. This causes the limiting block 55 to move up and down outside the measuring rod 51. Since the upper surfaces of the limiting seat 56 and the limiting block 55 are parallel, the upper surface of the limiting block 55 moves to the value aligned with the measuring rod 51 according to the required length, and then moves down, so that the limiting block 55 moves to the required value minus the distance between the blade tip and the limiting seat 56. This is to obtain the precise length of the cut flat knitting needle. By using the six sets of holes and placement slots provided in the placement seat 3 and the limiting seat 56, six sets of flat knitting needles can be cut simultaneously, increasing the working efficiency of the device.

[0031] according to Figures 4-5 As shown, during the process of measuring the required length of the knitting machine needle, the fixed block 54 also drives the connecting block 52 to rise and fall. The connecting block 52 then drives the extension plate 4 to rise and fall, causing the extension plate 4 to slide on the upper end of the support block 2. This allows the connecting block 52 and the extension plate 4 to simultaneously drive the cutting mechanism 6 and the fixing mechanism 7 to rise and fall. The electric telescopic rod 73 is opened, extending downwards and pushing the fixed plate 72 downwards. This causes the fixed plate 72 to drive the electromagnet 75 downwards, bringing the electromagnet 75 into contact with the tip of the needle. Then, the electromagnet 75 is energized, turning on the drive motor 66, which drives the bidirectional lead screw 65 to rotate. Because the bidirectional lead screw 65... The threads on both sides are opposite, causing the two L-shaped blocks 63 to move inwards simultaneously. The L-shaped blocks 63 drive the push block 61 to move, which in turn drives the two cutting blades 62 to move inwards simultaneously, so that the cutting blades 62 cut the needles of the flat knitting machine. At this time, the electromagnet 75 is energized to generate magnetic force, which attracts the debris and needle waste generated during cutting, preventing the needle waste from falling onto the surface of the limit seat 56 and affecting the cutting efficiency of the next cut. Then, the electric telescopic rod 73 retracts, driving the movable block 74 and the electromagnet 75 to move upwards, placing the waste box below the electromagnet 75. The electromagnet 75 is de-energized, losing its magnetic force, so that the debris and needle waste fall into the waste box, thus facilitating the collection of waste.

[0032] It should be noted that the aforementioned drive motor 66, electric push rod 53, and electric telescopic rod 73 can be powered by existing operating techniques, whether using a power supply device or an external wire. These are all conventional operating techniques and will not be described in detail here. The above is the working process of the entire device, and any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
